This document covers two issues, System error 81:01 and Media jams. Both issues require the same troubleshooting steps and parts to solve the issue. System error 81:01 is generated when there is a shutdown in the
Paper-Axis
motor, generally caused by a media jam. Causes also include a faulty Paper-Axis motor or
Electronics
module. Follow the steps listed below to accurately troubleshoot the issue, and replace the appropriate parts.

If any of the troubleshooting steps listed below solve the problem, attempt to verify printer functionality as instructed below. If functionality is verified, no additional parts should be replaced.

Turn the printer off.

Open the top cover and check for a media jam. Remove media if jammed.

NOTE: A manila folder can be used to aid in removing jammed media. Lift the blue lever and insert the folder into the media path to remove jammed media. Check inside both end covers to verify no media is lodged in these areas as well.

Turn the printer on.

If the error re-occurs, continue with the remaining steps (if no error appears verify functionality).

Ensure roll media is correctly installed on the media spindle, and verify that the roll is not larger than 150 ft in length.

NOTE: If media roll is to large for the printers spindle (greater than 150 ft), the roll can make contact with the media entry platen which can cause friction or hinder the media from peeling off the media roll smoothly.

Unplug the power cable from the back of the printer (printer will not allow power to be turned off using the power switch on the front of the printer).

Press and hold down the Up Arrow and Enter keys and plug in the power cable. Continue holding down both keys until a beep is heard.
